Scattered throughout the food and diet literature is the suggestion that to ensure optimal health we should return to the eating patterns before the 1960s. This concept was popularised by Michael Pollan. In his book In Defence of Food2 one of his ‘rules of thumb’ is ‘don’t eat anything your great-grandmother would not recognise as food‘. His implied take-away message is we should ‘eat real, proper, simple food’ – not the kind from a packet. When a recent article3 suggested going back two generations further ‘eat the way your great-great-great-grandparents ate, and you’ll live a long life’, it got me wondering.
To begin with, my great-great-great-grandparents number 32. To find out if that quoted statement is true, I would have to trace my family history back to those 32 ancestors, understand their backgrounds, work out what they probably ate, then contemplate whether foods they were eating in the manner they were eating them could improve my own longevity.
